Will the council need to approve it?
In England an annexe that stays part of the household and connects to the house is assessed as an extension, but its size usually takes it beyond permitted development, so a householder application describing the ancillary use is the normal route.
The planning position for a specific Stafford address depends on its history and any designations, which is why we check it at the first visit.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
Working in Stafford
Site visits are available across Stafford (ST16, ST17, ST18). The same team covers Rugeley (8 miles), Cannock (9 miles), Great Wyrley (11 miles), Burntwood (12 miles), all within easy reach.
For homes towards West Midlands, Bloxwich is around 14 miles away. Across the West Midlands, brick-built semis with long gardens are common, so single-storey and two-storey rear extensions are popular choices.
